[BUG] panic when making `eth_chainId` (and maybe others) just after `seid` started

[maoueh]

Seid version On seiv2 branch commit 01f00b30ad15cafdd2bb3bce5a16f64e85dc6728.

Chain ID Local chain via ./scripts/initialize_local_chain.sh

Describe the bug Panic when making an ETH JSON-RPC call not long after the chain booted.

To Reproduce Apply following diff to ./scripts/initialize_local_chain.sh:

diff --git a/scripts/initialize_local_chain.sh b/scripts/initialize_local_chain.sh
index bc29bd02..b0571c6e 100755

And run it, you should get following panic:

This is most probably solved by #1548, I'll test later when I have a chance.

[maoueh]

The panic went away with the way ChainID is defined. Still getting an error:

WARN [04-16|12:39:16.428] Served eth_sendRawTransaction            conn=127.0.0.1:51645 reqid=1 duration=1.173334ms err=": unknown"

Feel free to close if you think it's not relevant.
